Graded Pyrolytic Graphite/Silicon Carbide Coating Deposition Studies

Abstract

Codeposited coatings of pyrolytic graphite/silicon carbide were fabricated by chemical vapor deposition at temperatures ranging from 3000 F to 3800 F using methane and methyltrichlorosilane as precursors and nitrogen as a diluent and carrier. The effect of temperature and methyltrichlorosilane concentration on coating composition (SiC content) and morphology were determined. Specimens of codeposited coatings were fabricated to determine the physical properties, thermal stress state and erosion characteristics of various PG/SiC compositions. Coating samples were examined and characterized microscopically, by X-ray diffraction and by electron microprobe.
